Crowded Fire's production at Boxcar Playhouse is somewhat erratically paced and has sightline challenges, but it offers scope for some nicely tailored performances (with the most consistent work coming from Williams and Spencer, who anchor the proceedings with fine, vital turns). Emily Greene's half-open half-realistic scenic design, buttressed by Rebecca Longworth's mix of still and video backdrops, meanwhile strives with limited success to capture the play's particular mix of naturalism and supernaturalism.

That mixture is ultimately both a weakness and strength. The action can feel too mysterious, contradictory and diffuse to be as hard-hitting as it wants to be. But the boldness of Anderson's formal strategy and its deliberately spongy sense of history also invite an invigorating play between necessity and possibility.
